CVE-2026-58057

Flowise before 3.1.3 validates Custom MCP stdio environment variables against a denylist using a case-sensitive comparison, so on Windows, where environment names are case-insensitive, supplying 'nodeoptions' bypasses the NODEOPTIONS denylist entry. An authenticated user who can configure a Custo...
